The Effects of the Soils Thermal Field onto the Energy Performance of Buildings

The paper deals with the distribution temperature fields of soils at a real building object. These temperature fields are based on continuous (2 years worth of) measurements of temperature in certain depths of soils at a building structure. When designing buildings the climatic data are applied for a specific area only. Albeit in case of soils temperature the data are rather general, all locations do have the same values. One factor that significantly affects the soil temperature, are the thermal parameters inside and outside of buildings. The soils temperature is affected considerably by the structural solution used on a building, particularly in areas where thermal insulation is in contact with structures and the ground too. Whereas in case of soils there are no coherent outputs of temperatures with dependence to the characteristics of external and internal environment as much as to the structural solution of a building, the main aim of the paper is to make an impulse for the creation of comprehensive temperature data packs for soils for predetermined depths, structures and parameters of indoor and outdoor environment.

The Mean

Typical Meteorological Years (TMY) were prepared in Poland due to the introduction of obligatory energy certification for buildings. They are based on source data collected by the Institute of Meteorology and Water Management from 1971 to 2000. Predictions indicate that until the end of the 21st century, the air temperature will increase. Therefore, the characteristics obtained with the use of TMY may differ from the energy demand of buildings used nowadays. This article compares energy demand calculated with the use of TMY and subsequent climatic data from 2001 to 2012, for three different locations in Poland. The analyses were performed with the use of the dynamic simulation computer program, for typical living quarters in a multifamily residential building with different construction and window orientation. Results obtained with the use of TMY and subsequent climatic data show that the typical years can be used for the evaluation of heating demand. However, cooling demand calculated with the use of TMY was significantly lower in comparison with the mean cooling demand for the years 2001–2012. This may distort the energy needs and indoor environment conditions in summer, and cause discomfort or unnecessary energy use in presently occupied dwellings.

And Cluster Analysis

The definition of the building climate zones is the basis for studying the effects of urban climate on building energy consumption and efficiency. In Spain, the transposition of the European Directive on Energy performance of buildings (Directive 2010/31/EU) has been carried out through the Technical Building Code (CTE), which divides the territory into climatic zones through which it evaluates the energy performance of buildings. However, the CTE carries out a climatic division based on administrative criteria ("provinces", NUT3), which leads to oversimplifying the Spanish climatic reality.In this sense, the paper develops a new methodology for classification maps of climatic zones of buildings in Spain in order to improve the CTE. Therefore, the application in Spain of the CTE, K&#246;ppen and ANSI / ASHRAE methodologies are critically studied and compared. A first approach shows inadequacies that could be improve to optimize the energy efficiency of buildings. The climatic data for Spain -provided by the European Climate Assessment & Dataset Project (https://www.ecad.eu/) since 1950 (with a resolution of 1 km2/pixel) are analyzed, and a series of climatic indicators are established (such as the number of summer days, tropical nights, heating degree days, &#8230;). Next, OLS and cluster analysis are used as a method to define the Spanish climatic zones. Finally, the research proposes a new climate zones classification for Spain. The new classification provides more detailed climate information for building energy efficiency research and improves the classification defined in the CTE.
